{Scissiors moveable catenary system for electric railway depot}

The present invention relates to a vertical folding mobile cradle system for an electric railway vehicle base, and more particularly, to a portable cradle system for an electric railway vehicle, which is capable of preventing a safety accident such as an electric shock, The present invention relates to an electric railway vehicle base up-and-down mobile telecommunication line system capable of vertically moving a mobile electric car line up and down.

In addition to the opening of high-speed railway, electric railway which is attracting attention as a 21st-century new transportation means that it is necessary to improve the performance, reliability and security of electric railway line due to recent increase in speed and capacity of large electric railway, Is required.

Generally, the term "catenary line" refers to a catenary line such as a catenary line for supplying electric power in contact with a power train of an electric train, and facilities associated therewith.

The electric power required for running the electric train is supplied through the electric wire of the hypothetical electric car and the pantograph of the vehicle. The electric wire of the electric cable that supplies electricity to the electric train is classified according to the electric power feeding method. And the conditions of the railway line.

There are two types of cabling system: overhead system, rigid system, and third rail system. The cabling system of the cranes is classified into direct cranes and curtain cranes .

Conventionally, various types of crossover systems have failed to secure a sufficient working space in a series of operations related to inspection and maintenance of a vehicle other than the running of a train, in particular, maintenance and repair work on the upper part of the vehicle, There is a problem that safety accidents such as electric shock and fall may occur in an AC section using an extra-high voltage of 25 KV and a DC section using a high voltage of 1.5 KV, which are operated by a train.

Accordingly, the present inventor has proposed a motor bracket and a hinge (not shown) so that the electric wire can be moved into the inspection receptacle in the electric train vehicle base where the inspection and maintenance of the vehicle is carried out, as described in Korean Patent Publication No. 2006-0003941 By using the bracket to support the catenary, it is possible to secure a working space by turning part of the catenary to the wall of the checkup wall during the inspection and maintenance of the vehicle, and to prevent the safety accident of the operator. There is a bar.

However, as shown in Patent Document 1, when the electric wire is moved by using the motor bracket and the hinge bracket, an unnecessary moving space is generated due to the rotation radius of the first supporting bracket having a certain length when the first supporting bracket is rotated about the axis of the driving motor Therefore, when a plurality of driving motors move at the same time in order to rotate one electric wire, if the rotational speeds of the respective driving motors are different, the electric wire is twisted or bent and deformed, resulting in structural instability The durability is reduced, the structure due to the rotation is complicated, the manufacturing cost is high, the maintenance is frequently performed, and maintenance and management costs are increased.

In order to solve the problems contained in Patent Document 1, the present inventors have proposed a method in which a plurality of posts, each having one end fixed in a checker and having a predetermined length, are stretchable in the longitudinal direction as in the Japanese Patent Registration No. 10-0940767 (Patent Document 2) A movable metering line connected to the other end of the elongating and contracting means through an insulator and having a moving side conductive line fixed at a lower end thereof, a fixed metering line fixedly connected to the moving meteorological line and having a fixed side conductive line fixed at its lower end, And an electric contact portion for electrically contacting the end of the fixed electric wire and the moving electric wire, has been proposed.

However, in the case of Patent Document 2, a structure in which one end of the expansion / contraction means is horizontally expanded / contracted in the inspection vessel is deflected horizontally due to the weight of the moving electric wire and the own weight of the expansion / In addition, there is a problem that a sufficient space for extending and retracting in the left and right direction is secured. When applied to a subway car base or the like where the distance between the tracks of the vehicle track is short, If the expansion and contraction distances of the respective expansion and contraction means do not completely coincide with each other, there is a problem that the mobile electric wire is bent or twisted, resulting in a decrease in durability. To solve this problem, a complicated structure is applied .
